9.1.2 DC Output, RI-8000 – 1/R or inversely proportional to resistance
In insulation resistance, as described in 9.1.1 DC Output, RP-8000, if the
measuring voltage is constant, the current flowing through the sample is
halved, and the output voltage is also halved when the insulation
resistance -- R -- is doubled. This relation can be expressed as “1/R.”
The RI-8000 provides this type of DC signal output.
1) Specifications
Output Range: Full range of the measuring range of the SM-8200
Series super megohmmeter
Output Voltage: 10V/minimum value , 1 V/10 times minimum value
Output Accuracy: Within 10% of displayed value in the range from
minimum value to 10 times minimum value
2) Usage
Measure the insulation resistance of a sample with the method
designed in 6.1 Measuring Method. There is no limitation in the
applications in relation with the provision of the RI-8000 DC output.
Fig. 9.1.1 on the previous page shows the DC OUT (OPTION) “G”/”+”
terminals on the external input/output terminal block on the rear of
the unit.
